The carbon fixation occurs in the stroma, which is the colourless fluid that bathes the grana inside the chloroplast. It is in the stroma that the biochemical <span>reactions of reduction take place, one of them being</span><span> </span><span>carbon fixation. This is a light-independent reaction that is part of Calvin cycle. The stroma is where the enzymes that catalyse these reactions can be found.</span>
Answer:
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Chromatin structure plays a key role in regulating gene expression by allowing DNA accessibility to transcriptional machinery and transcription factors.
